In French, Mardi Gras means “Fat Tuesday.” It is celebrated the day after Shrove Monday and the day before Ash Wednesday as a last “fling” before the 40 days of self-denial of Lent, which precede Easter. Lent is a word that comes from the Middle English word “lente,” which means “springtime” — so named for the season of the year in which it usually occurs.

While the practice of Lent is not mentioned in the Bible, it has been a tradition in the Christian world since the mid-4th century. It seems to parallel the 40 days of fasting in the wilderness that Jesus experienced following his baptism at the Jordan River.

Origin of Mardi Gras

Historically, Lenten fasting became mandatory, especially abstinence from eating meat. While recommended by St. Athanasius, bishop of Alexandria in his Festal Letter III to his flock in Egypt in 331 AD, by the Middle Ages, Lent was enforced throughout Europe, especially the forbidding of meat during the last weeks before Easter.

Mardi Gras and Carnival

The word carnival comes from an old Italian word that means “go without meat” or “removal of meat.” Festivals like Mardi Gras sprang up throughout parts of Europe to prepare for the coming times of self-denial.

  • Venice was especially a “party town” for centuries with its Carnevale di Venezia and elaborate masks, which are still available in shops there today.
  • In England, the Tuesday immediately before Ash Wednesday is called Shrove Tuesday, following Shrove Monday, and is celebrated by eating rich food that won’t be consumed during Lent.
  • In the British Isles and some former countries of the British Commonwealth, Pancake Tuesday is a popular way of celebrating the day and eliminating rich foodstuffs from the pantry during Lent.
  • Brazil is famous for its Sambadrome Carnival parade. This year due to the Coronavirus pandemic, it will be not be holding its annual parade. The last time it was suspended was in 1912, following the death of the foreign relations minister.
